Here's an example I used. It's most commonly used on supply rails, but it's applicable to any signal.
 
As can be seen that I run the risk from both the directions . I'm not sure what the Crowbar would do when a 24VDC is already there and the accidental high voltages gets applied to the either terminals . Regards Ap |

| fast response time is necessary | 01/01/70 00:00 | |
| Look at an oscilloscope trigger circuit | 01/01/70 00:00 | |

| SCRs are slow! | 01/01/70 00:00 | |
| Zeners are slow! | 01/01/70 00:00 | |
| Slow? | 01/01/70 00:00 | |
| Try to convince the mechancis by arguing... | 01/01/70 00:00 | |
| Nice grip... | 01/01/70 00:00 | |
Maybe you can reverse the damage | 01/01/70 00:00 |
